The answer is B.<span> 3 : 5 = 12 : 20
2:3 doesn't equal 3:2 because they are backwards
42:7 doesn't equal 6:2 because 42:7 simplifies to 6:1 which is not equal to 6:2
14:6 doesn't equal 28:18 because 14:6 simplifies to 7:3 and 28:18 simplifies to 14:9, and these two proportions are not equal</span>

Answer: (3,-4)</h3>
Explanation:
The vertex of f(x) is (3,-6)
The vertex of g(x) is (3,-4). We keep the x coordinate the same, but add 2 to the y coordinate. This shifts the vertex 2 units up.
Answer:
simplify the equation to solve it, remove unnessecary parentheses and spaces.
Well each ladder has 30, and then it depends on how each person climbs their ladder. One climb at the rate of -2 per second. The other climb at the rate of 1 per second. Just x is equal to 1, that's why I didnt put 1x.
Equation: 30 + -2x = 30 + x
Answer:
x=5, y=6
Step-by-step explanation:
By the HL theorem, if the corresponding hypotenuses and one side of two triangles are equal, they are congruent.
So put the hypotenuses equal to each other, and put the side lengths equal to each other.
3x-2=2y+1
x=y-1
Sub 'y-1' into the first equation for x:
3(y-1)-2=2y+1
3y-3-2=2y+1
y=6
x=y-1=6-1=5
